Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of spray cooling, and more specifically, to a fan spray cooling device. Background Technology

[0002] With the continuous expansion of industrial production, the heat generated by mechanical equipment during operation has increased dramatically, placing higher demands on heat dissipation and cooling systems. Currently, fans are widely used for heat dissipation in the industrial sector. This method, which relies solely on fans to blow air, only removes heat by accelerating airflow through forced convection. Under high-temperature and high-load conditions, due to the limited heat capacity of air, air convection alone is insufficient to quickly and effectively dissipate the large amount of heat generated by the equipment, resulting in a significant reduction in heat dissipation efficiency. Especially in high-temperature environments during summer, or in scenarios where equipment operates continuously at high energy consumption, the equipment temperature remains high, affecting not only the normal operating efficiency of the equipment but also shortening its lifespan and increasing the risk of equipment failure. Furthermore, the single fan cooling method lacks flexibility and cannot be effectively adjusted according to different ambient temperatures and equipment heat generation. In addition, for some temperature-sensitive precision equipment, relying solely on fan cooling is insufficient to meet its stringent temperature control requirements.

[0003] Therefore, developing a cooling device that can effectively improve the shortcomings of existing heat dissipation is of great significance for ensuring the stable operation of industrial equipment and improving production efficiency. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a fan spray cooling device, which solves the technical problem that the heat dissipation method of the prior art, which relies solely on the blowing of a fan to remove heat by force convection to accelerate air flow, is difficult to dissipate the large amount of heat generated by the equipment quickly and effectively under high temperature and high load conditions.

[0005] According to one aspect, at least one embodiment of the present disclosure provides a fan spray cooling device, characterized in that it comprises:

[0006] The device includes a housing and several fan blades, the fan blades being installed inside the housing and rotating via electrical control.

[0007] An air intake filter assembly is disposed at the bottom of the housing;

[0008] A spray assembly, wherein the spray assembly is disposed on the top of the housing;

[0009] The spray assembly includes an outer ring frame, which is installed on the top of the outer shell and is fixedly connected to the outer shell by bolts. A protective net is provided on the outer ring frame. An outer ring cavity is opened inward around the top of the outer ring frame. A sleeve is fixedly connected to the top of the outer ring frame by bolts. Several nozzles are provided on the outer ring frame.

[0010] As a further technical solution, an inner ring frame is rotatably connected between the sleeve and the outer ring frame. A through cavity is opened around the outer surface of the inner ring frame, and the through cavity is connected to the outer ring cavity. A main pipe is fixedly connected to the top of the inner ring frame.

[0011] As a further technical solution, the main pipeline is connected to the cavity, a connecting seat is provided at the top of the protective net, and several distributed pipelines are connected between the connecting seat and the main pipeline, with the nozzles evenly distributed and connected to the distributed pipelines.

[0012] As a further technical solution, a raised layer is provided around the surface of the main pipe, a drive wheel that is driven to rotate by electricity is provided on one side of the outer shell, the end face of the drive wheel is in contact with the side surface of the raised layer, and a water inlet pipe is provided on one side of the outer ring frame.

[0013] As a further technical solution, the air intake filter assembly includes an outer groove, which is formed around the side surface of the outer shell. Several air inlets are formed at the top of the outer groove, and magnetic strips are provided at the top and around the side surface of the outer groove.

[0014] As a further technical solution, a pair of filter screens are installed inside the outer groove. The filter screens are magnetically attracted to the surface of the magnet strip, and both filter screens have a semi-circular arc structure.

[0015] As a further technical solution, the connection between the inner ring frame, the sleeve frame, and the outer ring frame is a right-angle bending transition structure.

[0016] As a further technical solution, the contact surfaces of the drive wheel and the convex layer are both anti-slip structural surfaces with high friction.

[0017] The beneficial effects of the embodiments disclosed herein are as follows:

[0018] In this disclosure, the spray assembly, through the design of an outer ring frame, an inner ring frame, a main pipe, and a distribution pipe, ensures that water is evenly sprayed from the nozzles and fully mixed with the airflow generated by the fan blades, creating a spray cooling effect. This solves the problem of low efficiency of relying solely on fan-driven cooling under high-temperature and high-load conditions. The drive wheel rotates the inner ring frame, causing the nozzles to rotate and spray, expanding the cooling coverage area, improving the uniformity and effectiveness of cooling, and quickly dissipating the large amount of heat generated by the equipment. This ensures the normal operation of the equipment in high-temperature environments and extends its service life. Attached Figure Description

[0031] like Figures 1-4 As shown, a fan spray cooling device according to an embodiment of the present disclosure is illustrated, comprising:

[0032] The housing 1 and several fan blades 2 are installed inside the housing 1 and rotated by electric control.

[0033] Air intake filter assembly 4, wherein the air intake filter assembly 4 is disposed at the bottom of the housing 1;

[0034] Spray assembly 3 is disposed on the top of the housing 1;

[0035] The spray assembly 3 includes an outer ring frame 3-1, which is mounted on the top of the outer shell 1 and is fixedly connected to the outer shell 1 by bolts. A protective net 3-2 is provided on the outer ring frame 3-1. An outer ring cavity 3-3 is formed around the top of the outer ring frame 3-1. A sleeve frame 3-4 is fixedly connected to the top of the outer ring frame 3-1 by bolts. Several nozzles 3-5 are provided on the outer ring frame 3-1. An inner ring frame 3-6 is rotatably fitted between the sleeve frame 3-4 and the outer ring frame 3-1. A through cavity 3-7 is formed around the outer surface of the inner ring frame 3-6 and is connected to the outer ring cavity 3-3. The inner ring frame 3-6 is fixedly connected to a main pipe 3-8, which is connected to the through cavity 3-7. The protective net 3-2 is provided with a connecting seat 3-9 at its top. Several dispersive pipes 3-10 are connected between the connecting seat 3-9 and the main pipe 3-8. The nozzles 3-5 are evenly distributed and connected to the dispersive pipes 3-10. A raised layer 3-11 is provided around the surface of the main pipe 3-8. A drive wheel 3-12 driven by electricity is provided on one side of the outer shell 1. The side end face of the drive wheel 3-12 is in contact with the side surface of the raised layer 3-11. A water inlet pipe 3-13 is provided on one side of the outer ring frame 3-1.

[0036] In some examples, to achieve dynamic and uniform coverage of the spray area, a spray assembly 3 is designed. This assembly includes an outer ring frame 3-1, which is bolted to the top of the outer casing 1. The outer ring cavity 3-3 at the top of the outer ring frame 3-1 and the through cavity 3-7 of the inner ring frame 3-6 form a rotatable fluid channel. The inner ring frame 3-6 is rotatably fitted between the outer ring frame 3-1 and the sleeve 3-4. The through cavity 3-7 on the outer surface is radially aligned with the outer ring cavity 3-3. When the inner ring frame 3-6 rotates, the through cavity 3-7 and the outer ring cavity 3-3 remain in communication, ensuring that the water flow is evenly distributed to each nozzle 3-5. The sleeve 3-4 is fixed to the top of the outer ring frame 3-1 to support the inner ring frame 3-6 and restrict its axial movement. The main pipe 3-8 is connected to the through cavity 3-7, and multiple nozzles 3-5 are connected to the top through the dispersing pipe 3-10. The nozzles 3-5 are evenly distributed along the circumference, covering the area above the fan blade 2.

[0037] The drive wheel 3-12 on one side of the outer casing 1 is driven to rotate by a motor. Its end face is in contact with the protrusion 3-11 on the surface of the main pipe 3-8, and the friction drives the inner ring frame 3-6 to rotate. When the fan blade 2 rotates to deliver air, the rotating nozzle 3-5 sprays water mist in a spiral shape, which is fully mixed with the airflow to achieve a spray cooling effect. The water inlet pipe 3-13 is connected to the outer ring cavity 3-3. Water flows through the outer ring cavity 3-3, the through cavity 3-7, the main pipe 3-8, and the dispersion pipe 3-10 and is sprayed out from the nozzle 3-5. The protective net 3-2 is installed between the outer ring frame 3-1 and the outer casing 1, which not only prevents debris from entering the spray assembly 3, but also disperses the sprayed water mist, making the droplets more uniform.

[0038] like Figures 1-4 As shown in the figure, the air intake filter assembly 4 in this embodiment includes an outer groove 4-1, which is formed around the side surface of the outer shell 1. Several air inlets 4-2 are formed at the top of the outer groove 4-1. Magnet strips 4-3 are provided at the top and around the side surface of the outer groove 4-1. A pair of filter screens 4-4 are installed in the outer groove 4-1. The filter screens 4-4 are magnetically attracted to the surface of the magnet strips 4-3. The filter screens 4-4 are all in a semi-circular arc structure.

[0039] In some examples, to achieve efficient air filtration and convenient maintenance, an air intake filter assembly 4 is designed. This assembly includes an outer groove 4-1 that is formed around the side surface of the outer casing 1. This outer groove 4-1 serves as an air intake channel, and the air inlet 4-2 at the top is connected to the outer groove 4-1. When air enters the outer groove 4-1 from the air inlet 4-2, it must pass through the semi-circular filter screens 4-4 on both sides. The magnetic strips 4-3 on the top and side surfaces inside the outer groove 4-1 are made of neodymium iron boron permanent magnet material, which magnetically attracts the metal frame of the filter screen 4-4, making the filter screen 4-4 fit tightly against the inner wall of the outer groove 4-1 and preventing unfiltered air from bypassing it. The filter screen 4-4 adopts a composite structure of metal frame and polyester fiber filter material. Its semi-circular design matches the curvature of the outer groove 4-1, and it can be pushed in or pulled out along the curvature of the outer groove 4-1 for easy and quick replacement.

[0040] The arrangement of the magnetic strips 4-3 forms three magnetic defense lines. The top magnetic strip 4-3 secures the top of the filter screen 4-4, while the side surface magnetic strips 4-3 secure the two side edges, ensuring that the filter screen 4-4 does not fall off under airflow impact. Dust particles are intercepted on the filter screen surface, and cleaning can be completed by periodically pulling the filter screen 4-4. The annular structure of the outer groove 4-1 ensures that air is evenly distributed to each air inlet, avoiding excessive local airflow that could lead to filter failure. Combined with the negative pressure generated by the fan blade rotation, this effectively reduces pollutants such as dust and oil in the air, protects the internal components of the fan from wear, and extends the equipment's lifespan.

[0041] For example, such as Figure 4 As shown, the connection points between the inner ring frame 3-6, the sleeve frame 3-4, and the outer ring frame 3-1 all have right-angle bending transition structures.

[0042] In some examples, the connection between the inner ring frame 3-6 and the sleeve frame 3-4, and the outer ring frame 3-1, adopts a right-angle bend transition structure. This design balances structural rigidity and rotational sealing. The inner side of the right-angle bend is usually provided with a rounded chamfer to avoid cracking caused by stress concentration, and at the same time facilitates the smooth rotation of the inner ring frame 3-6 within the outer ring frame 3-1. For example, after the lower end face of the inner ring frame 3-6 is bent at a right angle, it fits against the top surface of the outer ring frame 3-1 to form a radial sealing surface, ensuring that the water flow is continuously and evenly sprayed from the nozzle 3-5, and avoiding spray interruption or flow deviation due to loose connection.

[0043] For example, such as Figure 1 As shown, the contact surfaces of the drive wheel 3-12 and the convex layer 3-11 are both anti-slip structural surfaces with high friction.

[0044] In some examples, the contact surfaces of the drive wheel 3-12 and the raised layer 3-11 are both high-friction, anti-slip structural surfaces. This design ensures uniform coverage of the spray angle by enhancing transmission reliability. When the drive wheel 3-12 is driven to rotate by the motor, the frictional torque generated by the anti-slip surface can be stably transmitted to the raised layer 3-11, driving the inner ring frame 3-6 to rotate at a constant speed, so that the nozzle 3-5 forms a 360° uniform spray area above the fan blade 2. In addition, the wear-resistant properties of the anti-slip structural surface can extend the service life of the transmission components. Even in environments where the surface is wet due to long-term spraying, it can still maintain a stable driving force, ensuring that the cooling device maintains a uniform spray effect during continuous operation and avoiding problems such as insufficient cooling or excessive humidity in some areas due to unstable rotation speed.

[0045] In actual use: The outer casing 1 is fixedly installed, and the fan blade 2 rotates inside the outer casing 1 under electric control. External air enters from the air inlet 4-2 of the outer groove 4-1 at the bottom of the outer casing 1, and enters the outer casing 1 after being filtered by the filter screen 4-4 adsorbed by the magnetic strip 4-3. Water flows into the outer ring cavity 3-3 from the water inlet pipe 3-13 on one side of the outer ring frame 3-1, and enters the main pipe 3-8 at the top of the inner ring frame 3-6 through the through cavity 3-7 connected to the outer ring cavity 3-3. Then, it is sprayed out from the nozzle 3-5 through the dispersion pipe 3-10. At the same time, the drive wheel 3-12 on one side of the outer casing 1 is electrically driven to rotate. Its side end face is attached to the protrusion 3-11 on the surface of the main pipe 3-8, which drives the inner ring frame 3-6 to rotate between the sleeve frame 3-4 and the outer ring frame 3-1, so that the nozzle 3-5 sprays water mist evenly. The water mist mixes with the airflow generated by the rotation of the fan blade 2 to cool the equipment.
